It can take 48 hours especially as big as the game was. Once the winnings are announced you go to your profile there you can request a payout or save it for another game.
Due to sickness I forgot to do the final weigh-in on time. I still feel like a winner though! I've met my goal without exercising. Just walking the dog, taking care of my two kids and being pregnant (I was cleared by my midwife to do this DB, due to high BMI and it being saver for the baby if I lost a bit of weight). So no final weigh-in, no money-win this time. But I'm still a winner nonetheless!
